| Abstract: | Objective: To determine the chain length of polyprenol homologues from Ginkgo biloba leaves. Method: Poly prenol homologues of high purity are separated from the petroleum ether extract of Ginkgo biloba leaves. This polyprenol homologues are analysed with RP HPTLC, using acetone as developing solvent and staining them with iodine vapours. Result: Compared with the polyprenols standard, they can be the polyprenol 15 to polyprenol 21. Conclusion: The chain length of polyprenol homologues can be determined easily with HPTLC. Comparing with HPLC, method of HPTLC costs lower. |
